Command Syntax |
|
8.2.3 |
vlan database |
Use the vlan database privileged EXEC command to enter VLAN
configuration mode from the command-line interface (CLI). From the CLI,
you can add, delete, and modify VLAN configurations and globally
propagate these changes by using the VLAN Trunking Protocol (VTP). |
vlan database |
| |
vlan vlan_number |
Use the vlan VLAN configuration command to configure VLAN
characteristics. Use the no form of this command to delete a VLAN and
its configured characteristics. |
nvlan vlan-id [name vlan-name] [media {ethernet | fddi | fdi-net |
tokenring | tr-net}]
[state {suspend | active}] [said said-value] [mtu mtu-size] [ring
ring-number]
[bridge bridge-number | type {srb | srt}] [parent parent-vlan-id]
[stp type {ieee | ibm | auto}] [are are-number] [ste ste-number]
[backupcrf {enable | disable}] [tb-vlan1 tb-vlan1-id] [tb-vlan2
tb-vlan2-id] |
| |
switchport access vlan vlan_number |
Use the switchport access interface configuration command to configure
a port as a static-access or dynamic-access port. If the mode is set
to access, the port operates as a member of the configured VLAN. If
set to dynamic, the port starts discovery of its VLAN assignment based
on the incoming packets it receives. Use the no form of this command
to reset the access mode to the default VLAN for the switch. |
switchport access vlan {vlan-id | dynamic} |
| |
show vlan |
Use the show vlan command to display VLAN information. Each Ethernet
switch port and Ethernet repeater group belong to only one VLAN.
Trunk, FDDI/CDDI, and ATM ports can exist on multiple VLANs. |
show vlan typer |
| |
vlan 2 name VLAN2 |
Use the vlan VLAN configuration command to configure VLAN
characteristics. Use the no form of this command to delete a VLAN and
its configured characteristics. |
vlan vlan-id [name vlan-name] [media {ethernet | fddi | fdi-net |
tokenring | tr-net}]
[state {suspend | active}] [said said-value] [mtu mtu-size] [ring
ring-number]
[bridge bridge-number | type {srb | srt}] [parent parent-vlan-id]
[stp type {ieee | ibm | auto}] [are are-number] [ste ste-number]
[backupcrf {enable | disable}] [tb-vlan1 tb-vlan1-id] [tb-vlan2
tb-vlan2-id] |
| |
switchport mode access |
Use the switchport mode interface configuration command to configure
the VLAN membership mode of a port. Use the no form of this command to
reset the mode to the appropriate default for the device. |
switchport mode {access |
trunk} |
| |
vlan static |
On a Catalyst 1900, this command is used to statically assign ports to
an interface. |
vlan static |
| |
show vlan-membership |
On a Catalyst 1900, this command is used to show port assignments to
VLANs. |
show vlan-membership |
| |
show vlan id |
This command shows information specific to the VLAN chosen. |
show vlan id id_number |
|
8.2.4 |
show vlan |
Use the show vlan privileged Exec command to display the settings of
VLAN configuration parameters. |
show vlan [vlan] |
| |
show vlan brief |
Gives a short synopsis of the VLANs created including VLAN number,
VLAN name, VLAN status, and the ports assigned |
show vlan brief |
|
8.2.6 |
switchport access vlan 300 |
Use the switchport access interface configuration command to configure
a port as a static-access or dynamic-access port. If the mode is set
to access, the port operates as a member of the configured VLAN. If
set to dynamic, the port starts discovery of its VLAN assignment based
on the incoming packets it receives. Use the no form of this command
to reset the access mode to the default VLAN for the switch. |
switchport access vlan {vlan-id
| dynamic} |
|
8.3.4 |
debug sw-vlan packets |
This command is used to display general information about VLAN packets
that the router received but is not configured to support. |
debug sw-vlan packets |
| |
show sw-vlan |
VLAN packets that the router is configured to route or switch are
counted and indicated using this command. |
show sw-vlan |
|
8.3.5 |
show interface |
Use the show interface privileged EXEC command to display the
administrative and operational status of a switching (nonrouting)
port. |
show interface [interface-id
| vlan number] [flow-control | pruning | status | switchport [allowed-vlan
| prune-elig | native-vlan]] |
| |
show int status |
Verify that the duplex and speed are set properly between the switch
and the router. |
show int status |
| |
show vtp status |
Use the show vtp privileged EXEC command to display general
information about the VLAN Trunk Protocol (VTP) management domain,
status, and counters. |
show vtp {counters | status}
| [{begin | exclude | include} expression] |
| |
no vtp password password |
Use the vtp password VLAN configuration command to configure the VLAN
Trunking Protocol (VTP) administrative domain password. Use the no
form of this command to remove the password. |
no vtp password password-value
|
